I've searched google and can't find anything, but one place selling replacement remotes.

It seems like there is something i'm doing to disable the alarm. Any chance its just a loose wire or something? Or is it something with some feature of the alarm. It worked when i bought it i stopped working that night, and its worked sporadically since then. And it disarms with the same button again (with a double tone) and unlocking the doors. The problem is sometimes the alarm arms itself (makes a single tone of the siren) when you lock the doors with the remote, and sometimes it doesn't. The right button doesn't seem to do anything. When you hit the left button the doors lock, hit it again the doors unlock. The remote also controls the power door locks. I followed the wires, found a little on/off switch under the dash, its not a kill switch, but i can't see anything else the wires lead above the fuse box. And there are stickers on the windows that say checkmate, and same with the siren under the hood. I know nothing about this alarm accept its made by Checkmate, here is a of the remote. When i bought my car it came with this alarm.
